这项研究的目的是测量一组巴西成年人牙根表面的龋齿患病率。对年龄35~44岁和50~59岁的牙科患者(男女各360人)根面龋损的患病率及其口腔内分布进行了研究。98.9%的患者根面有牙龈凹陷，78.1%的患者至少有一处根面龋损。使用根面龋齿指数(RCI)分析该疾病的患病率。女性的平均值(18.6%)高于男性(13.4%)(p<；0.01)，两个年龄组的平均值相似(p>；0.01)。上颌尖牙、第一前磨牙和下颌磨牙的RCI值最大。RCI在上颌近侧面和下颌颊侧面较大。我们的结论是，巴西人口中存在根面龋病，值得关注它们在成人主要口腔疾病流行病学中的实际作用。
The aim of this study was to measure the caries prevalence in the root surface in a group of Brazilian adults. The prevalence and their intraoral distribution of caries lesions of root surface were assessed in dental patients ranging in age from 35 to 44 and from 50 to 59 years of age of both sexes (n=360). A total of 98.9% had root surfaces with gingival recession and 78.1% had at least one root caries lesion. The prevalence of the disease was analyzed using the Root Caries Index (RCI). The average value was greater for women (18.6%) than for men (13.4%) (p<0.01) and similar in both age groups (p>0.01). The maxillary canines and first premolars and the mandibular molars presented the greatest RCI values. The RCI was greater in the proximal surface of the maxilla and buccal surface of the mandible. We conclude that caries of the root surface are present in the Brazilian population and deserve attention concerning their actual role in the epidemiology of principal oral diseases of the adult population.
